[VoIP] Zaptel end-of-dialing

[Shane Young]

Again, there are several ways to skin a cat (or dialplan)...

If you dial 18217301#
Your EXTEN variable is set to 18217301#.

When it's passed to the macro, the variable name is MACRO_EXTEN
You could use ${MACRO_EXTEN:0:11) to skip 0 digits and use the next 11  
digits, this eliminating the 12th digit (#)

The nice thing is you can use the same thing even if you don't dial the #.
It will still skip 0 digits and use the next 11.


Another way might be to do something like this:

[somecontext]
exten => _1X.,1,Macro(dial-cnet)
exten => _1X.#,1,GoTo(somecontext,${EXTEN:0:11},1)

The first one would just fire after the timer and follow the normal path.
The second one would loop back and "start over" as if you had dialed  
the number without the # ad the end, but would not wait for any  
addtional digits.  It would then pick the first entry.





the voip-info wiki gives information about the use of substrings  
within a variable:

http://www.voip-info.org/wiki/index.php?page=Asterisk+variables

Substrings
    ${foo:offset:length}

returns a substring of the string foo, beginning at offset offset and  
returning the next length characters.

If offset is negative, it is taken leftwards from the right hand end  
of the string.
If length is omitted or is negative, then all the rest of the string  
beginning at offset is returned.

Examples:

    ${123456789:1}        - returns the string 23456789
    ${123456789:-4}       - returns the string 6789
    ${123456789:0:3}      - returns the string 123
    ${123456789:2:3}      - returns the string 345
    ${123456789:-4:3}     - returns the string 678

Examples of use:

    exten => _NXX.,1,SetVar(areacode=${EXTEN:0:3})   - get the first 3  
digits of ${EXTEN}
    exten => _516XXXXXXX,1,Dial(${EXTEN:3})          - get all but the  
first 3 digits of ${EXTEN}
    exten => 100,1,SetVar(whichVowel=4)

    exten => 100,2,SetVar(foo=AEIOU:${whichVowel}:1) - sets ${foo} to  
the single letter 'U'
